Data Sheet
General Information
The Keysight Technologies, Inc. N4376D Lightwave Component Analyzer (LCA) is the instrument of
choice to test short wavelength 10G Ethernet, Fibre Channel FCx8, FCx10 and FCx16 electro-optical
components, with up to 26.5 GHz modulation range. The N4376D also supports the test of transmit-
ter and receivers for optical computer backplanes and optical chip-to-chip connections in high speed
computers and server applications.
Modern optical transmission and datacom systems require fast, accurate and repeatable charac-
terization of the core electro-optical components. These core subcomponents (lasers, modulators
and detectors) have significant impact on the performance of the transmitter and the receiver with
respect to modulation bandwidth, jitter, gain, and distortion of the final transceiver.
For frequency dependent responsivity measurements the N4376D extends opto-electronic
S-parameter measurements to multimode devices in the 850 nm wavelength range.
With the latest PNA family of network analyzers, the N4376D guarantees excellent electro-optical
measurement performance. In addition a unique new calibration concept significantly reduces time
from powering up the LCA until the first calibrated measurement can be made. This increases
productivity in R&D and on the manufacturing floor.
The fully integrated "turnkey" solution reduces time to market, compared to the time-consuming
development of a self-made setup.
The electrical and optical design of the N4376D is optimized for lowest noise and ripple. IIn addition,
this design makes the accuracy independent of the electrical reflextion coefficient. It's the excellent
accuracy that improves the yield from tests performed with the N4376D, by narrowing margins
needed to pass the tested devices. Traceability ensures world-wide comparability of test results.
The advanced optical design together with temperature-stabilized transmitter and receiver ensures
repeatable measurements over days without recalibration.
Using the advanced measurement capabilities of the network analyzer, all S-parameter related
characteristics of the device under test, like responsivity, ripple and 3 dB-cutoff frequency, can be
qualified with the new N4376D Lightwave Component Analyzer from 10 MHz to 26.5 GHz.
The network analyzer
The N4376D is based on the new 2- and 4-port N5222A PNA Series microwave network analyzer
with an identical and well known user interface across all Keysight network analyzers. Versions
with configurable test set and bias-T integrated in the network analyzer are available. The High RF
output power ensures a higher optical modulation index (OMI). This gives you the freedom to change
between small signal analysis and large signal analysis of your device under test. True mode
balanced measurements are possible with 4-port, dual source network analyzers.
